Jenkins automatically runs all tests for all build configurations. The regressiontests results are show on the Jenkins page under "Test" and a test report looks like this.

Jenkins also automatically computes the code coverage. This is currently only done when the regressiontests are modifified not when the tests are modified. The code coverage of the regressiontests for the 4.5 source is here and for the regressiontests and the unit tests together for the master branch source is here.
